Application filed October 11, 1926 Serial No. 140,723.-

The present invention relates to extension rims for the drive wheels'of planters, and other analogous implements.

As is well known to those familiar with planters and other like types of seeding implements, it is the usual practice in such implementsto derive the power for operating the seeding mechanism from one of the wheels of the implement,such wheel generally being referred to as the-drive wheel. In many instances, it is desirable to increase the effective diameter of this drive wheel so as to obtain a slower rate of seeding or a greater traction efficiency. 1 7

It is the fundamental objectof the present invention to provide-an improved extension rim for mounting on such drive wheel, whereby this greaterdiameter is obtained. To facilitate mounting the extension rim on the wheel, and to obtain maximum compactness for shipping, storing and handling, it is desirable thatjthe rim'bedivided into a plurality of sections; and-in this regard it is a further object of my in- 2 vention to provide a sectionalized rim wherein all sections of the rim are duplicate, interchangeable units. In consequence of this, all sections of the rim'are made from the same pattern; there are no, rights or lefts; 80 and it is impossible to assemble .the rimimproperly on the drive wheel.

' A further object of the invention is to provide improved means for mounting the rim sections on the drive wheel, such being preferably accomplished by providing the rim sections with clamping portions extend ing therefrom and arranged to embrace the rim or felloe of the drive wheel.

Other objects and advantages of my in- 40 vention will be apparent from the following detailed description of a preferred embodiment thereof.

In the drawing accompanying this description:

Figure 1 is a. side elevational view of-a planter, illustrating my improved extension rim mounted on the drive wheel thereof.

Fig. 2 is a similar view of the drive wheel removed and showing the present rim l mounted thereon.

Fig. 3 is a fragmentary elevational view of the tread surface of the extension rim,

illustrating the overlapping relation between the ends of the rim sections.

Fig. 4 is a transverse sectional view taken on the plane of the line l lfof Fig. 2, and i Fig. 5 is a transverse sectional view taken on the plane of the line 5-5 of Fig. 2.

For illustrating a typical adaptation of my inventionl haveshown in Figure .1 a conventional design of one-row planter,

comprising a drive wheely? and the usual furrow opener 8 and covering wheel 9. The

furrow opener and covering wheel are made adjustable, relative to the frame 11, so as to compensate for the greater diameter of the extension rim. The drive from the wheel 7 to the seeding mechanism is in accordance with .any standard practice, part ofv the transmission gearing being generally .enclosed in a housing '12 which affords a bearing support for the drivewheel 7 Fig. 2 illustrates the preferred type of 'drivewheel to which my extension rim has application. The wheel is cast with the hub 13, the spokes 14 and rim or felloe 15, all integral. The hub 13 is generally recessed on one side andis provided with bolt holes 13 for'receiving bolts by which the wheel hub is secured to an .inner hub, which inturn carriesthe'bevel gear of the usualv power transmission train.

. Referring to Figs. 5 and-6, it will be observed that the rim or felloe 15 of thedrive wheel'is V-shaped incrosssection with the apex of the Vfacing outwardly. The inner periphery of this rim is preferably formed with a shallow head 16 which merges into the spokes 1 1. Traction lugs or grousers 17 project outwardly from the inclined side surfaces 15 of the wheel rim, such lugs or grousers preferably alterating between 019- posite sides of the rim.

The extension rim is dividedinto a plurality of sections 19, which may be of any desired number, although for the usual size of drive wheel employed on one-row planters I find it preferable to divide this extension rimintothree sections. As before described, these sect-ions are all duplicate, interchangeable units, preferably made as castings. In their general formation, such units preferably follow the construction of the wheel rim, being'of V-shaped cross section with the apex facing outwardly and withintegral lugs or grousers 21 projecting outwardly in alternating sequence from the opposite sloping sides of the rim sections. The inner peripheral surface of each rim section is formed with a plurality of spacing lugs 22 which are adapted to bear on the-uter periphery of the :wheel rim: and space the rim sections a The ends of therim sections join with an overlapping joint, as shown in. Fig. 3. This joint 'is obtained by torining in each end ofeach section a scarf or notch 23Wl1ich leaves -ranwextending half portiontherefrom.

the scarf or notch atrrone end is-locatedcon ysloping side surface ozfithe wheel rim, andthenunclines inwardly .to form the aperlured= boss -25 extencliiigxpaiit Way across the inne1'=rpe1'iphe1'y of thewheel rim. The

clampingdugs "of adjoiningrim sections lie in the same transverse: plane, and the .alined holes 26 therein receive bolts 27 by which eac'li kpair i of clamping lugs is. drawn: into finmuengagement: WllJh thB Wheel rim. One

lug 0t each rim section is: formed with a square socket-or"counterbore 28 for receiving the-square shank portion 27 of the bolt, this preventing theibolt from turning as the nut 296s being drawn ups Each clamping lug is reinforced by a radially extending rib 31 and: byza semi-circular rib "33. WVhen assembled on the drive Wheel, the extension rims is held against slipping circumferentiallyiby the engagementflof the clamping lugs 25" with theuspokes 14: and with the grousers 17 onthe Wheel rim.
